Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78556, here are decompositions:

3 + 78553 = 78556
17 + 78539 = 78556
47 + 78509 = 78556
59 + 78497 = 78556
89 + 78467 = 78556
239 + 78317 = 78556
353 + 78203 = 78556
383 + 78173 = 78556

Showing the first eight; more decompositions exist.
